BM14C Stainless Steel Column Load Cell
Stainless steel column cell from 0.5 t to 50 t with OIML R60 C3 and C4 approval.
Product Overview
The BM14C takes the column cell concept into stainless steel and stretches the range down to 0.5 t. Hermetically welded, anti reversal and self aligning, it is the cell to specify where a heavy weighing point also has to survive corrosive gas, washdown or salt, and it carries OIML R60 approval in both C3 and C4.

How It Compares
| HM14C alloy steel column cell | Same structure, different material and range. The HM14C is alloy steel from 10 t; the BM14C is stainless steel from 0.5 t and carries OIML R60 C3 and C4. |
|---|---|
| B8D stainless shear beam | The B8D is a low profile beam up to 10 t. Use the BM14C where compression loads are higher or a self aligning column mount suits the deck. |

BM14C Stainless Steel Column Load Cell Questions
Why choose a stainless column cell over alloy steel?
Because the outside of the cell matters as much as the seal. In salt, brine or chemical atmospheres an alloy steel body corrodes externally even when it stays watertight.
How low does the capacity range go?
0.5 t, which is unusually low for a column cell and useful where one family has to cover several weighing points.
Which accuracy classes carry OIML approval?
C3 and C4, with n max of 3000 and 4000 respectively.
